Abstract (en)

An engraving head (1) comprises a mechanism for reciprocatingly moving an engraving stylus (7) within the housing (2) of the engraving head. The movement mechanism comprises: a movable body (5) which is movable along with an inner circumference of a movement space (3c) formed in an inside of the body housing (2); and a first energizing means (8) for energizing the movable body in a direction away from the engraving face. The movable body is energized by a second energizing means which includes the compressed gas in a direction nearer to the engraving face against an energizing force of the first energizing means, thereby the tip portion of the engraving stylus moves with a movement of the movable body in the direction nearer to the engraving face, while by releasing the energizing force of the second energizing means which includes the compressed gas, the tip portion of the engraving stylus moves with the movement of the movable body in the direction away from the engraving face. <IMAGE>
